HERMANN MAYR, OF AUGSBURG, GERMANY, ASSIGNOR TO ROBERT LISSNER, OF BERLIN, GERMANY.

PIN HINGE FOR DOORS AND WINDOWS.

Application filed September 11, 1922.

To all whom it may concern:

Be it known that I, I'TERMANN MAYR, a citizen of the German Republic, residing at Augsburg, Germany, have invented certain new and useful Improvements in Pin Hinges for Doors and Vindows, for which I have filed application for patent in Germany on the 12th September, 1921, Patent No. 358480, of which the following is a specification.

This invention relates to a butt hinge for doors, windows and the like with. eccentrically arranged pivot pin, the characteristic novel features of which are that the pivot pin is made in one piece with the upper part of the hinge and arranged eccentrically to the axis of the butt hinge and engaging with an eccentric boring in the lower part of the hinge.

The butt hinge has no lateral flaps, but each part of the same. has a flat contacting surface which facilitates the fixation of the hinge upon the dooror window-frame.

An embodiment of the invention is shown by way of example on the accompanying drawing, wherein: i

Fig. 1 is a front view and Fig. 2 a side elevation of the butt hinge in the position of the parts when the door is open.

Fig. 3 is a plan view.

Fig. 4 is a similar view as Fig. 3 showing the hinge made from special profile iron.

The butt hinge consists of the two parts a and 6 designed to be fixed respectively on the door and on the door frame by means of strong wood screws inserted through two holes 0, c and d, d in the two parts of the hinge. The claws h of the parts of the pin hinge are thus pressed into the wood so that the parts of the hinge are securely held in position.

The pin 6 forms an extension at the lower end of the upper part .7) of the butt hinge and the boring g of the lower hinge part a is also eccentric. The upper hinge part Z) has a contact surface f and the lower hinge part a has a contact face f, so that the door cannot jam at the lower part of the hinge if it is being opened, as owing to the eccentricity w the upper hinge part turns with little play on the lower hinge part.

The lower hinge part a has a boring g with which the pin 6' engages by its pointed or spherical end, so that oil in the boring lubricates the hinge continuously.

Serial No. 587,487.

The butt hinge can be made of iron, bronze or the like in different sizes and it presents the advantage that it can be used at the right edge as well as at the left hand edge of doors or windows.

The butt hinge may further be made from special profile iron rod as shown in Fig. 4: and the pin 6, instead of being made in one piece with the upper part b may be inserted in an eccentric boring of this part.

I claim 1. A hinge for doors and windows comprising in combination a lower hinge part having an eccentric bore, an upper hinge part, and a pivot pin forming an extension at the lower end of the upper hinge part and standing eccentric to the axis of the main cylindrical portion of this hinge part and engaging with said eccentric bore of the lower hinge part.

2. A hinge for doors and windows comprising in combination a lower hinge part having an eccentric bore, a flattened contact face on the outer surface of said lower hinge part, claws on the outer surface of the lower hinge part designed to penetrate into the door frame or window frame, an upper hinge part, and a pivot pin forming an extension at the lower end of the upper hinge partand standing eccentric to the axis of the main cylindrical portion of this hinge part and engaging with said eccentric bore of the lower hinge part.

3. A hinge for doors and windows com: prising in combination a lower hinge part having an eccentric bore, an upper hinge part, a flattened contact face on the outer surface of said upper hinge part, claws on the outer surface of said upper hinge part designed to penetrate into the frame of the door or window frame, and a pivot pin forming an extension at the lower end of the upper hinge partand standing eccentric to the axis of the main cylindrical portion of this hinge partand engaging with said eccentric bore of the lower hinge part.

In testimony whereof I affix my signature in presence of two witnesses.
